Abstract We discuss the mode of galaxy evolution based on merging after binary encounters, complementary to the mode based on direct hierarchical collapses. We show that the merging-driven mode produces, mainly by dynamical evolution, a local Schechter-like luminosity function starting at z ~ 2 from a steep mass distribution like Press & Schechter's. Such evolution inside galaxy systems provides a quantitative estimate of the Butcher-Oemler effect and yields an excess of faint blue galaxy counts like that observed.
